MACHINE FORMAKING PAPER SHELLS.

SPECIFICATION forming part of Letters Patent No. 454,113, dated June 16, 1891. Application filed September 19, 1890. Serial No. 365,453. (No model.)

To all whom t may concern,.-

Be it known that I, GEORGE B. FARRING- TON, a citizen of the United States, residing at Unionville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Making Paper Shells; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has for its object to produce a machine for making winding shells for paper-that is to say, shells or spools of the class described in Letters Patent to Farrington and Curtis, No. 411,140, dated September 17, 1889. In order to enable me to produce these shells at a maximum speed and at the minimum of cost of production, each shell being perfectly made and all being of uniform quality, I have devised the novel machine which I will now describe, referring by numerals to the accompanying drawings, forming part of this specication, in which* Figure 1 is a plan view of the machine complete; Fig. 2, a longitudinal section of the winding-roller; Fig. 2, a cross-section of the winding-roller, as at so x in Fig. 2; Fig. 3, a left side elevation as seen in Fig. l; Fig. 3, a detail view illustrating the construction and operation of the prong upon the swinging lever; Fig. 4, a right-side elevation as seen in Fig. 1; and Fig. 5 (see Sheet 1) is a detail sectional View of a completed paper shell, showing the metallic hub or bushing in place.

l denotes frame-work, of any suitable or preferred construction. Power is applied to the machine by means of a belt (not shown) running over a pulley 2, loosely mounted on a shaft 3, one end of which .has its bearing in the frame-work and the other in a bracket 4..

5 denotes a clutch member, which slides longitudinally on the shaft and is controlled by a lever 6, which in the present instance I have shown as pivoted to the floor. I have not deemed it necessary to illustrate the details of construction of the clutch, as any ordinary clutch can be used. It is sufficient for the purposes of this speciiication to say that member 5 is provided with clutch proj ections (not shown) which engage corresponding projections on the hub (not shown) of the belt-pulley. The object of this construction is to enable the operator to stop and start the operative parts of the machine without removing the main belt from the belt-pulley. Shaft 3 is provided with apinion 7, which engages a gear S on a shaft 9, which has its bearings in the opposite sides of the frame-work. At the other end of shaft 9 is a pinion 10, which engages an intermediate pinion 11. This pinion in turn engages a pinion 12 on the shaft of a carrying-roller 13. Pinion 12 in turn engages a pinion 14 on the shaft of a roller 15, which rotates in a glue-tank 16, this glue-tank being indicated by dotted lines in Figs. 3 and 4. The bearings for the carrying-roller are shown as in the sides of brackets 17. 18 denotes the winding-roller, which is shown as loosely mounted in the top of brackets V17. The glue-roller 15 is shown as having its bearings in the top of the framework. It will of course be understood that these details of construction are wholly immaterial so far as the gist lof my invention is concerned, and may be greatly varied without departing from the principle thereof.

19 denotes a transferring-roller, which rests upon the top of the winding-roller and the glue-roller, said transferring roller having no journals and receiving its motion from windin g and glue rollers. Glue from the tank is picked up by the glue-roller and is by roller 19 transmitted to the surface of the paper that is being wound on the Winding-roller. This construction prevents any Inore glue than the required amount to saturate the paper being conveyed thereto, and also permits the Winding of shells of any required size. The construction Of the winding-roller is clearly illustrated in Figs. 2 and 2, The body of this roller is made in three parts, two of which (denoted, respectively, by 18L and 18h) are semi-cylindrical in cross-section and taper on their inner sides from end to end.

1Sf denotes a wedge-shaped piece, which is placed between parts 1S and 18D in assembling the roller and acts to force said parts outward. The outer end of the wedge is turned down, as clearly shown in Fig. 2, and serves as one of the journals of the roller.

18c denotes a head, which is cast integral IOO with part 1S and is provided with a socket 1S on its inner side and a journal 13G, extending from its outer side. One end of part 18J is adapted to engage the socket, as is clearly 5 shown in Fig. 2. The parts are held in operative position by a ring i814, which is slid over the three parts of the body, as shown,

the ring clamping the parts together and holding them in the assembled position. At the 1o outer end of the turned-down portion of the wedge is an opening 18, which is adapted to be engaged by a prong 2O on a lever 2l, pivoted to the frame-work and adapted to be swung outward therefrom when it is desired to withdraw the wedge from between the other parts of the roller.

In order to provide a suitable tension during the operation of winding without strain upon the saturated paper, I provide tensionzo levers 22, having weights 23 suspended from their outer ends, the inner ends of said levers being pivoted to brackets 2l. These levers rest upon the journals of the winding-rollers and act to press the latter down upon the carry- 25 ing-roller, it being understood, of course, that the winding-roller receives its motion from the carrying-roller and that the transferringroller is in contact both with the windingroller and the glue-roller.

In Fig. 5 I have illustrated one end of a winding-shell ready for use. The body of the shell is indicated by 25.

27 denotes metallic hubs or bushings having fianges 2S and .enlargements 29, substan- 3 5 tially the same as in the patent to Farrington and Curtis, referred to. There is, however, this difference in the enlargement: Instead of being made angular, as shown in the patent referred to, the forward end thereof is an 4o are of a circle, and the enlargement is made of less diameter than the flange, so as not to extend through the shell proper, as in said former patent. In practice the shell is wound to the precise diameter of the flange, and the 4 5 hubs or bushings are driven into place and riveted or otherwise secured, as in the said Farrington and Curtis patent.

30 denotes a recess in the end oi' the completed shell, which receives enlargement 99.

5o This recess I form by means of a saw 3l, mounted in suitable bearings on a bracket 32, which extends upward from the frame-work. The shaft which carries the saw is provided with a belt-pulley 33. Motion is imparted to the saw by a belt 3l, passing over pulley and vover a pulley 35 on shaft 3o' (see dotted lines,'Figs. l and 3) denotes a roll of paper from which the shells are wound. The roll of paper is carried by a shaft 37, de-

6o tachably mounted in bearings on the framework, the shaft being provided with the usual sliding cones 3S, which engage the bushings of the shell upon which the paper is wound, or the ends of the shell itself, if a metallic shell is used. The cones are locked in position upon the shaft by bolts 39 or in any vsuitable manner. In order to provide a tension on the roll of paper, so that the unwindingthereof maybe controlled, I place a pulley l0 on shaft 37.

il denotes a strap which partially encireles this pulley and engages a staple or hook 42 on the short arm of a bell-crank lever 43, This lever is pivoted to the frame-work, as clearly indicated in Fig. l, the long arm thereof extending downward to the opposite end of the machine and being adapted to engage the teeth of a rack il., (Shown only in dottedlines in Fig. 4.) The operator obtains the desired amount of tension on the roll of paper by pressing down on the long arm of the lever and catching it upon one of the teeth of the rack.

l5 is a rest which supports the paper as it passes to the windingroller. This rest is preferably provided with a rib LLC, which extends from the opposite ends of the rest inward and forward, the apex of the rib being at the forward end of the rest, so as to support the paper at the center and prevent the possibility of sagging. This insures even winding of the paper on the winding-roller to form the shell.

The operation of the machine is as follows: The end of the roll of paper is passed over the rest and over the top of the carrying-roller and is wound about the winding-roller, the paper being thoroughly saturated with glue before passing over the winding-roller by contact with the transferring-roller. As already stated, the winding-roller is prevented from turning freely by the pressure of tension-levers 22 on the journals thereof. It will be apparent that this retarding of the rotation of the wi nding-roller, in connection with the pressure of the transferring-roller, insures the greatest possible degree of hardness in the completed shells. \Vhen the shell upon the winding-roller is wound to the required thickness, the operatorstops the rotation thereof by movement of lever G, throwing the clutch members out of engagement. He then removes the winidngroller, with the shell thereon, from its bearings and proceeds to remove the shell from the roller. For convenienceatable-l? is provided, upon which the wound shell may be laid. The operator then knocks ring 18g off from the end of the body of the winding-roller, engages prong 2l in the opening 18 in the end of the wedge, and by means of lever 2l, or in any suitable manner, withdraws the wedge from between the parts of the body of Ithe windingroller, holding the shell meanwhile with one hand. The withdrawal of the wedge permits part 1S of the winding-roller to fall inward, so that it may be readily removed, after which the shell maybe removed from the other part of the body. The operator then,by means of the saw, makes the recesses 30 at the ends of the shell to receive the enlargements on the hubs or bushings. The bushings are then driven into the ends of the shell and secured by riveting, as 1n the former patent referred to, or 1n any suitable or preferred manner.

and the Winding-roller, and tension-levers 22, 1

Which engage the journals of the Winding'- roller, as and for the purpose set forth.

3. The combination, with a Windingroller, a carrying-roller, a glue-roller, and a transferring-roller, substantially as described and shown, of a rest Which supports the paper as it passes to the Winding=roller, said rest being' provided With a rib inclining inward and forward from the opposite ends of the rest, the center of the paper being supported by the apex of the rib, so as to prevent sagging.

at. The combination, with a Winding-roller, a carrying-roller, a glue-roller, and a transferring-roller, substantially as described and shown, of a shaft 37, having suitable cones to engage the shell of a roll of paper, a pulley 40, a strap partially encircling said pulley, aud a bell-crank lever having a staple engaged by said strap, whereby any required amount of friction may be placed on the roll of paper.

5. A winding-roller consisting of two semicylindrical parts, a Wedge adapted to lie between said parts, one end thereof serving as one of the journals of the roller, and a ring adapted to clamp the parts together, one of said parts having a head With a journal projecting outward therefrom and on its inner side a socket to receive the end of the other part, substantially as described and shown.

In testimony whereof I affix my signature in presence of two Witnesses.
